BOOK-STAPLING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 512,741, dated January 16, 1894.

Application filed August 12,1893. Serial No- 483,042. (No model.) .Patentedin Germany July 4, 1891, No 63,254. and in France November 12, 1891, N0. 217,393.

To all wlwm it may concern.-

Be it known that I, JULIUS THEODOR Orro ORTLOFF, a subject of the Grand Duke of Ba den, and a resident of Heidelberg, in the Grand Duchy of Baden, Empire of Germany, have invented certain new'and useful Improvements in Book-stapling Machines, with a device for putting the sheets on and off, (for which pate'nts have been obtained in Germany, N 0. 63,254, dated July 4, 1891, and in France, No. 217,393, dated November 12, 1891,) of which the following is an exact specification.

My invention relates to a book-stapling machine, which is provided with a device for putting the sheets on and off and constructed in such a manner that the sheets are first stapled and then folded. 1 By this arrangement the efficiency of my machine is much greater than is the case in stapling-machines with a separated folding-machine, because in my machine simultaneously one sheet is stapled and another folded. This result is attained by the arrangement of feeding-rollers, serving for conducting the sheets to the stapling mechanism, and of folding-rollers,by which the sheets, after having been stapled, are folded together. The latter circumstance is highly important for sheets, which must be quickly folded, suc

as newspapers, pamphlets and so on. A

In order to make my invention more clear, I refer to the accompanying drawings,in which similar letters denote similar parts throughout the different views and in which- Figure 1 is a side-view. Fig. 2 is a frontview of my improved machine. Fig. 3 shows the heads for forming the staples in two different positions. t

In carrying my invention into effect, I construct my machine in the following manner:

Z is the frame of the machine having at its upper end a crank shaft A supported by suit able bearings and driven by a pulley P. At the free end of the crank shaft A there is secured a crank lever L attached to the slide K, which, together with the head K, is guided in the guide-pieces O O of arm 0, the latter forming part of frame Z. The staples are formed in the head K. Opposite to this latter, there are arranged between the guidepieces N N fixed to the arm N of frame Z, the anvil U and the slide U, which latter is likewise fixed at a crank lever M and moved during the stapling process. The head K and the anvil U are connected with the slides K and U respectively by angular pieces Q and T pivoted at the arms 0 and N of the frame Z and having slots at b and c d, in which the pins efand g h attached to the headsK and U are sliding.

' X X are two upright arms of the frame of which X supports two feeding rollers W W serving for leading the sheets'of paper from the table T to the stapling device by means of the endless band Y guided over the roller W andthe folding roller F. The rollers W W are rotated from the pulley F. connected with the pulley E on shaft A by the endless band C.

The double armed lever V pivoted in the center of folding roller F is operated by the cam-shaped roller F and serves for raising the sheets a little before being folded.

G G is a double-armed folding-lever pivoted to the arm 0 and provided with the folding knife J. This lever G G is actuated by the cam G V is a stop for securing the position of the sheets to be folded.

The manner of operation of the machine is as follows: The sheets are put from the table T between the feeding rollers W W and conveyed to the anvil U and head K by the endless band Y. By the movements of the head K and anvil U, as shown in Fig. 3 of the drawings, the sheets are stapled and then led to the folding rollers F F. Here the folding knife J presses the sheets betweenthe rollers F and F and thereby folds them together in the manner illustrated by Fig. 1.

I do not confine myself to the exact form of construction shown in the drawings, as I may arrange of course more than two folding rollers before or behind the stapling device and employ several anvilsU and heads K. Therefore, 7

What I desire to secure by Letters Patent of the United States is 1. In a book-stapling machine, the combination with the stapling device proper of feed rollers W W, arranged one above the other, delivery rollers F F arranged one in front of the other, and transporting bands Y running over the rollers W and F and between head K and anvil U of the stapling device, a folding-knife I secured to arm G being arranged above the space between the delivery rollers, for the purpose as described.

2. In a book stapling machine, the combination withthe staple-forming-headKandthe staple-bending-anvil U, held and moved by slides K and U respectively, of feed-rollers W W arranged one above the other, delivery-rollers F F'arranged one in front of the other, transporting bands Y running over the rollers XV and F and between head K and anvil U, the latter two being connected with the slides K and U by levers Q and T having slots at b and c d, pins 6 h fixed to the head and anvil taking into the slots a and d respectively, and pinsf g fixed to the slides taking into the slots 1) and 0 respectively, a folding knife I secured to double-armed levers G G being arranged above the space between the delivery rollers, said lever being actuated by cam G on the main shaft A, for the purpose as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
